Study Tip
Remember Newton’s Third Law of Motion (“for every action, there is an equal and opposite reaction”) in order to better understand how a rocket is thrust upward into space.
Rockets
A rocket is propelled into shape by particles flying out of one end at high speed
- Fuel is ignited in a chamber → explosion of gases → pressure that forces gases out of rocket → rocket moves in opposite direction
- Thrust: reaction force of gases which push the rocket forward
